Quick answer
Conductivity is the reciprocal of resistivity, in siemens per metre, and one siemens per centimetre is 100 S/m. It is the standard measure of water purity: ultrapure water sits near 5.5 microsiemens per metre while seawater is around 5 siemens per metre, roughly a million times higher.
| Siemens per metre (S/m) | 1 |
| Millisiemens per metre (mS/m) | 1000 |
| Siemens per centimetre (S/cm) | 0.01 |
| Mho per metre (℧/m) | 1 |
About the Electric Conductivity Converter
Electrical conductivity is a material property describing how well it conducts current, the inverse of resistivity. The SI unit is the siemens per metre.
It is used in materials science and in measuring the purity of water and other solutions.
Frequently Asked Questions
What is electrical conductivity?
⌄
It is a material property describing how readily it allows electric current to pass, the reciprocal of resistivity.
What is the SI unit?
⌄
The SI unit is the siemens per metre (S/m).
Why is water conductivity measured?
⌄
Conductivity indicates how many dissolved ions water contains, which is used to assess water purity and quality.
